GALVANIC BELT.

SPECIFICATION forming part of Letters Patent No. 246,051, dated August23,1881.

Application filed December 20, 1880. (No model.)

To all whom it may concern:

Be it known that I, HENRY O. IVARNER, of

Gilroy, in the county of Santa Clara and State vanic belts to be wornabout the person for curative purposes.

It relates both to the construction of the voltaic elements or pairs ofwhich the belt is composed, and to the manner of connecting themtogether to produce a perfect and continuous action throughout theentire number of elements, as shown in the drawings, and hereinafterdescribed.

Figure 1 shows a portion of my improved belt, the remainder of whichwould be only a repetition of the elements and connections. Fig. 2 is atop or edge view of Fig. 1. Figs. 3, 4, 5, 6 are details of the partsused in forming the circular elements of the battery.

I make the elements A of my belt from four disks, to a I) b, of properpositive and negative metals, and I place them so as to have the twoinner ones, 11 b, in contact, and the two outer ones, a a, facing them,but separated by means of the washers c c, of material usually employedfor such purpose. Each element is formed in this way of an outer diskofone metal, a second disk of metal positive or negative to the firstone and separated from it by a washer, 0, a third disk of metal ofopposite nature to the second disk and placed directly against it, and,lastly, a disk on the outside, which is of a metal positive or negativeto the last-named disk, and is separated from it by a washer, c. Allthese parts are secured together by means of an insulated rivet, d, thatpasses through a central hole made for it through all the disks. Iprefer to make these disks of circular form, as shown in the drawings,and by employing them in the manner described I produce a battery orelement of small size and light weight, but of increased power. Inconstructing a belt of these elements I can employ a less number than isrequired of other kinds of such elements and still obtain the properstrength and continuity of action. I thus greatly reduce the cost ofmanufacture, not only in the quantity of metal required, but chiefly inthe time and labor of fur ishing and fitting the parts together.

There is an extension or ear, E, formed on one side of the disk a byextending the metal, and having a. slot or hole, f, to receive the ringor link f. The shape of this extension is such that a suflicicntquantity of metal is provided between this hole and the edge of the diskto prevent the link from pulling or cutting out.

These ears are provided on the outside disks, 0,

of each battery and on alternate sides, so that when two or morebatteries, A, are brought together the car on the outside disk of oneshall be connected to the car on the inside disk of the next battery;andin a belt formed of such elements a continuous connection of an innerto an outer disk is made throughout the entire length, as shown in Figs.1 and 2 of the drawings.

Connection between the ears E is made by rings or links f, which notonly join the elements together, but also act as conductors from oneelement to the next one, so as to give the required continuity of actionthrough the several elements of the belt. In order to keep the belt inthis continuous working condition, it is necessary to preserve thegalvanic contact and connection at all times between the severalelements while the belt is in place around the body, and for suchpurpose to prevent the oxidization of the inner surface or edges of theholes and the surface of the connecting-links when they pass throughthese holes. I therefore maintain the belt in a. state of tension, whenin use, by inserting at one or more points in the length of the beltacoil-spring, Gr, Figs. 1 and 2. These springs join two of the elementstogether, and act also as conductors between them, and when the belt isclasped around the body the elasticity thus given to it causes the ringsor links to be always in metallic contact with the edges of the holes inthe extensions E, and by their rubbing action while thus in a state oftension upon the person the surfaces of the rings and the edges of theholes are kept clean and bright and the perfect con tact of the surfacesinsured as long as thebelt is worn.

This construction and manner of putting together the parts gives a morepowerful and more durable belt than is obtained by any of the kindsnowknown to me. The construction, moreover, greatly simplifies the costand labor of producing the parts and putting them together, and thus itmaterially reduces the cost of manufacture, while giving a betterarticle. A. single central rivet or fastening unites the several partsof an element firmly together, and a single short link is all that isrequired to connect one element to another. The required effect isobtained with a minimum amount of *metal, and the amount of hand-laborrequired to produce and join the elements into a continuous battery isvery small. WVhen the required number of these elements are joinedtogether, as before described, I inclose them Within a tube, D, of clothor textile material, so that they are covered on all sides, and thistube I attach by bands or loops to a Waistband or supporting-belt, asshown at Fig. 1. By this means I protect the battery from atmosphericinfluence and action in a great degree, and thereby prevent theexciting-liquid from being too quickly evaporated, While I also keep thebattery from soiling and staining the clothing and person of the wearer.The action of the elements is rendered more uniform and lasting by beingthus inclosed Within a protecting-tube. From various points in this beltthe current is conducted and applied to the parts to be treated by meansof suitable conductors in the usual manner.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

The electric beltherein described, consisting I of the two centralplates, 1) b, of dissimilar metals, their inner faces resting againsteach other, the outer disks or plates, to a, each of dissimilar metal tothe metal of the central disk adjacent thereto, and having extensionsHENRY CONRAD WARNER.
